Title: Turbo-molecular pump
Inventor: ASHIDA OSAMU
IPC: F04D19/04
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To reduce the sticking of a reaction product to a rotor blade of a turbo-molecular pump. SOLUTION: In this turbo-molecular pump, a rotor blade 1 is supported on a bearing unit including magnetic bearings 10 and 11, rotating it at high speed, whereby gas exhausts are carried out. In this case, a purge gas is fed to the downstream end or its end inside of the rotor blade 1, and thereby an inrush of exhaust gas to at least the downstream inside of the rotor blade is prevented. The purge gas fed to the downstream end or its inside of the rotor blade inhibits the inrush of exhaust gas to the downstream end inside of the rotor blade, and further it prevents any reaction product from being stuck and accumulated to the downstream end inside.

Abstract: PROBLEM TO BE SOLVED: To prevent generation of mechanical, electrical or chemical stress at the joint of electric conductor forming a stator winding, by forming the joint in the shape of ball at the time of jointing an electrical conductor included in the stator with the stator. SOLUTION: A joint 33f is formed by the TIG welding, after end portions 33d of the neighboring conductor segment 33 are provided adjacently while these are in contact with each other, by providing closely a nozzle including a tungsten electrode to the adjacent area. For example, when a conductor segment 33 is formed of copper having a higher thermal conductivity, such segment is fused up to the area near the end portion 33d at the time of welding, and therefore entire part of the joint 33f is rounded by the surface tension to become a ball shape having no edge portion. Moreover, thickness (T) of the joint area 33f becomes larger than the thickness (t) of the rectangular cross-sectional conductor of the conductor segment 33. Moreover, width W of the joint 33f becomes larger than Width W×2 of two rectangular cross-sectional conductor of the conductor segment 33.

Abstract: PURPOSE:To perform writing coupling from the exterior without melting by forming an amorphous Si layer added with no impurity in an Si wiring layer or between wiring layers, and emitting an energy quantum beam as conductivity. CONSTITUTION:An amorphous Si layer 6 added with no impurity is formed between n<+> type layers 3, 4 on an Si wiring film 2 on an Si substrate 1. When the wirings 3, 4 are coupled, a laser light ray or the like is emitted to the layer 5 to convert it to polysilicon, thereby activating the contained impurity as conductive state. When this system is used, no scattering of the wiring layer due to the melting exists, thereby obtaining an external writing IC device having high reliability.

Abstract: PROBLEM TO BE SOLVED: To prevent the peeling of a resist, the deformation of a pattern, the defective opening of the pattern, etc., by treating a wafer with a basic solution after a silicon oxide film formed on a substrate is isotropically etched with a hydrofluoric acid solution by using a resist pattern formed on the silicon oxide film as a mask. SOLUTION: After a resist film 3 is formed on a silicon oxide film 2 formed on a substrate 1 (A), a via hole pattern having an opening of a diameter 31 is formed (B). Then the silicon oxide film 2 is isotropically etched with a buffer hydrofluoric acid solution (C) and, after washing the substrate with water, the pattern is deformed to a prescribed size 33 by removing an affected resin layer 32 with a basic solution (D). After performing washing with water, spin- drying, dehydrating baking, and dry etching on the substrate 1 (F), a via-hole pattern is formed by removing the resist (F). Therefore, the peeling of the resist can be prevented by eliminating the volumetric shrinking of the surface of the resist and the occurrence of a reaction between the resin from which a protective group is eliminated and an noniopic activator, etc., can be presented.  In addition, the slump and crush of the via hole can be prevented.

Filed: 1995-06-09
Abstract: PURPOSE: To realize an electrically heating structure which eliminates uneven heating with a high assembling productivity. CONSTITUTION: A U-shaped heater 11 is sandwiched vertically by notches provided in two sheet metal parts, a heat insulating plate 17 is provided previously inside a high temperature part of a subheating chamber 16 and the area of opening of tiny holes positioned below the end part of the heater 11 is smaller than that of those right below the center part of the heater 11 in the top surface of a heating chamber. With such an arrangement, a wiring from one side is sufficient to supply power to the heater 11 while the assembling is completed simply by placing parts sequentially. This reduces the number of parts and simplifies the mounting thereof while the quantity of radiation can be uniformized from right below the center part to below the end part in the irradiation of the object to be heated from a tubular heater through the tiny holes thereby eliminating uneven heating.

Title: Foil-wound transformer
Inventor: OOKUBO HITOSHI
IPC: H01F27/28
Filed: 1982-08-20
Abstract: PURPOSE:To reduce the current concentration and heat generation due to the eddy-current loss at an end part of a conductor and increase the strength against a short-circuiting mechanical force, by providing a cylindrical winding which permits current capacity to be selected as desired on the outer periphery of a foil winding. CONSTITUTION:The outermost periphery of a foil winding 5 is wound with two-layer cylindrical windings 21, 22 employing a conductor other than a foil conductor, such as a rectangular condcutor or the like. The outermost peripheral cylindrical winding 22 is shorter in winding stack than the inner cylindrical winding 21. Further, an interlayer insulator 23 is disposed between the inner cylindrical winding 21 and the foil winding 5. The cylindrical winding 21 is wound so as to closely contact the foil winding 5 and clamp the same from the outside. An interlayer insulator 24 is also interposed between the inner and outer cylindrical windings 21 and 22. Thus, there is a large increase in strength against a short-circuiting mechanical force acting on the high-voltage winding 5. By passing the eddy current concentrated on a point B on the winding outer peripheral part to the cylindrical winding, it is possible to greatly reduce the concentration of eddy current on the foil winding conductor, and the heat generation can be suppressed.

Title: Calculation method for predicting current zero-point and detecting system thereof for synthesizing test
Inventor: FURUHATA TAKAAKI
IPC: G01R19/175
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To predict a current zero-point without errors, even if a DC content is included in the current. SOLUTION: Conventionally, a current zero-point is predicted by linear approximation using the data for 2 points of current. However, error becomes large, because current change near zero-point was not linear if the current contains a DC content. Now, the zero-point of current is predicted by three-point approximated value 1, using current 3-point data Ia , Ia-1 , and Ia-2 , for allowing prediction even if curved current changes near a zero-point. From the simultaneous equations, factors A, B, and C are obtained, and a time (t) until a current zero- point is obtained from an equation At<2> +Bt+C=I.

Title: Electric dust collector with an excitation control type facial plasma source
Inventor: MASUDA SENICHI
IPC: B03C3/00
Filed: 1978-11-21
Abstract: PURPOSE: To obtain high dust collecting performance by repeatedly making the operation in which exciting voltage is supplied to an excitation control type facial plasma source to generate plasma and the negative charge of dust particles on dust collecting plate is neutralized during the zero voltage period of high-tension ripple main voltage.  
     CONSTITUTION: A negative high-tension ripple main voltage is applied across the discharge plate group 28 and the dust collecting plates 33 and 33' to supply negative ions to the dust collecting plates 33 and 33', whereby floating dust particles in gas coming into the spaces 40 and 40' from the gas inlet 24 are deposited and adhered to the dust collecting plates 33 and 33'. Then, during the time when the main voltage is zero, an exciting voltage occurs from the exciting power source 6 and a facial plasma appears on the dust collecting plates 33 and 33'. The positive ions in the  plasma 9 are attracted by stored negative charge on the dust layer on the strip elec  trode groups 2, 2', 2"..., thus resulting in the complete neutralization of negative  charge. The repeated neutralization of the negative charge enables dust to be collected while suppressing the generation of reverse electrolytic dissociation even if the  electric resistance of dust to be collected is high.
